Agata [3.3K]3 years ago

5 0

Answer:

four electrons

Explanation:

Let us attempt to write the electronic configuration of carbon in the ground state. This electronic configuration will now be;

C- 1s2 2s2 2p2

The outermost principal energy level of carbon is the n=2 level which houses the 2s2 and 2p2, making a total of four electrons in the outermost principal energy level of an atom of carbon in the ground state.

A 1.9 L reaction vessel, initially at 298 K, contains nitrogen gas at a partial pressure of 337 mmHg and oxygen gas at a partial

Arturiano [62]

Answer:

The pressure of N₂O₄ in the reaction vessel after the reaction is 290 mmHg

Explanation:

Nitrogen gas reacts with oxygen gas to form dinitrogen tetroxide.

N₂ (g) + 2O₂ (g) → N₂O₄ (g)

Therefore since by Avogadro's law equal volumes of all gases contain equal numbers of molecules, there fore as the gases are within the same vessel, thier partial pressure is equivalent to their concentration

from the reaction, 1 mole of N₂ react with 2 moles of O₂ to produce 1 mole of N₂O₄

Thus

1 mmHg of N₂ react with 2 mmHg of O₂ to produce 1 mmHg of N₂O₄

337 mmHg N₂ ×(1 mmHg of N₂O₄/ 1 mmHg of N₂) = 337 mmHg N₂O₄

580 mmHg O₂ ×(1 mmHg of N₂O₄/ 2 mmHg of O₂) = 290 mmHg N₂O₄

As seen from the above calculation, the limting reactant is oxygen and the partial pressure of N₂O₄ = 290 mmHg

How many moles of HNO3 will be produced 3 NO2+H2O=2HNO3+ NO

valkas [14]

Answer:

2 moles of HNO3

Explanation:

The equation seems to be balanced correctly. The problem is we done know what you started with. We will assume it is 3 moles of NO2.

If that is the case then 2 moles of HNO3 will be produced.

Which describes the process that forms teflon tm? molecular fluorine (f2) undergoes polymerization. a fluorocarbon polymer break

Stella [2.4K]

Answer:
T<span>etrafluoroethene (F</span>₂CCF₂<span>) undergoes polymerization describes the formation of Teflon.

Explanation:
Polymerization is the process in which small units called as monomers join together repeatedly and forms a long chain macro-molecule called as polymer.
In given question the monomer is Tetrafluoroethene because alkenes can undergo polymerization via Addition polymerization via following mechanism.
a) Free Radical Addition Reaction

b) Acid Catalyzed Addition Reaction

c) Base catalyzed Addition Reaction

The formation of Teflon from Tetrafluoroethene is shown below,</span>

The molecular mass of propane-1,2-diol is 76.1 amuamu . Calculate the molecular mass of propane-1,3-diol, an isomer of propane-1

sashaice [31]

Answer:

76.1 amu

Explanation:

Let us recall that isomers refer to two different compounds with the same molecular formula but different atom to atom connectivity and different chemical properties. When two compounds are isomers, we can essentially represent them with exactly the same molecular formula.

Now propane-1,2-diol and propane-1,3-diol are both represented by the molecular formula C3H8O2 since they are isomers of each other. When two compounds have the same molecular formula, they must essentially have the same molecular mass. Hence the molecular mass of propane-1,3-diol is also 76.1 amu.
